problem building gtk+ 2.10.13

[dcottingham00 comcast net]

I've run into a problem building gtk+ 2.10.14.  My distro has an older version of
gnome, and I'm trying to install an application that requires a more up-to-date
gtk+; but I don't want to replace the system library, since that will likely break
everything else.  So my approach is to build gtk+ and the libraries it depends on
into a separate prefix.  

So glib 2.12.13, cairo 1.2.4, and pango 1.16.4 have all been installed into the
prefix /home/dc/local/AU/1, PKG_CONFIG points to /home/dc/local/AU/1/lib/pkgconfig,
LD_LIBRARY_PATH points to /home/dc/local/AU/1/lib.  "./configure --prefix=/home/dc/local/AU/1"
is happy, including reporting that it found glib version 2.12.13.  But "make", after
much effort, fails here:

/bin/sh ../libtool --mode=link gcc  -DG_DISABLE_DEPRECATED -g -O2 -Wall   -o gtk-query-immodules-2.0  queryimmodules.o libgtk-x11-2.0.la ../gdk-pixbuf/libgdk_pixbuf-2.0.la ../gdk/libgdk-x11-2.0.la

./.libs/libgtk-x11-2.0.so: undefined reference to `g_bookmark_file_get_is_private'
... and then many more undefined references.

Is this failing because it's searching the glib in /usr/lib before the new one in
/home/dc/local/AU/1/lib? If so, why is it doing this?  Any ideas how I can debug this?

Thanks,
